1 Claim.

This invention relates to door fastenersv forcombination storm and screen doors, and has for 'an object to provide fasteners which will permit H a storm insert 'pp'e d with a window .12.

i -For removably securingthebottom of the insert sets-y applicauon of the insert, either screen or window sash, to the door frame.

A further object is to provide fasteners which I type which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order. v

With the above and other objects in view invention consists of certain novel details of conto the lower railii of the door frame a tongue member 14 is provided, as best shown in Figure -8.

tongue member is 'iormed of sheet metal,v

one end portion of which is imperforate to form a tongue. The other end portion is severed longitudinally to provide astraight prong l5 .disaposed in alignment with the tongue. The material on each side of the straight prong is bent on thesame' side of the prongto extend at a I right angle to the prong as shown at It and is then bent to extend in a plane parallel to the prong II and form spaced prongs ll. All'of the prongs are sharpened at the-ends.

A pair of tongue members maybe applied to thetop surface of the bottom rail "l3 oi the door by driving the prongs into the wood, the bent portion It being used as an abutment against struction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from ,the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming a part of this specification-- Figure 1 is a front elevation of a door equipped with a storm insert secured by fasteners constructed in accordance with the invention.

Figure 2 is an enlarged front elevation of'one of the sliding type fasteners, showing the insert' in section to expose the wearplate and belt.

Figure 3 is an enlargedcross sectional view taken on the line 33 of Figure 1.

Figure 4 is a longitudinal sectional view of the insert and bottom rail of the door secured by pronged fasteners constructed in accordance with the invention.

Figure 5 is a detail perspective view of the holder of the sliding time fastener.

Figure 6 is a detail perspective view of the bolt which slidably fits in the holder.

Figure 7 is a detail perspective pronged wearplate.

Figure 8 is a detail perspective view of the pronged tongue for securing the bottom of the insert tothe bottom rail of the door frame.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, ll designates a door frame,

view of the which a hammer may be struck to drive the prongs into the wood.

The tongue of the tonguemember is received in a recess l8 formed in the bottom surface of the insert II and to prevent the wood chipping 5 off at the entrance to this opening a wearplate I9 is provided, best shown in Figure-7.. The wearplate is formed of sheet metal and is of substantially oblong contour. The wearplate is provided centrally with a slot 2!! to receive the tongue of the tongue member ll. Triangular prongs ii are formed at the corners of the wearplate and extend from the same side of the wearplate, at a right angle to the wearplate. These pron s are driven into the wood of the insert so'that the slot 20 of the wearplate registers with the open end of the recess iii. The

tongue of the tongue member thus engages the edges of the slot 20 so that the wear'is taken upby the wearplate and not by the wood.

The fasteningdevices for securing the insert to the, door frame each comprise, see Figures 5 and 6, a holder formed from a blank of sheet metal bent longitudinally upon itself to provide a channel 22 and bent above the channel to provide lateral wings 23 extending in the same plane and provided with openings 24 to receive round-headed screws 25 for securing the device to the door frame side stile, as shown in Fi ures 1, 2 and 3. A bolt member, formed from sheet metal, is slidably received in the channel, one end of the bolt having a narrow tongue 21 formed integral therewith and bent to extend perpendicular to the bolt, as shown in Figure 6, the. tongue terminating in a flat knob 28 adapted to engage the outer faces of the wings as shown in Figure 2.

' The bolt is adapted to engage in a recess 29 formed in the insert side stile I2 and to prevent chipping of! of the wood at the entrance end of the recess a wearplate 30 similar to the wear-' plate above described is secured to the insert side stile l2 and is provided with triangular shaped prongs 3| which extend at a right angle to the wear plate and are adapted to be forced into the wood to anchor the wearplate in place. The wearplate is provided with a slot 32 to receive the bolt,26.

In applying the fasteners to the upper portion of the doorframe III the holder member is secured in a recess 33 in the side of the door, as best shown in Figure 3, so that the wings 23 are flush with the surface of the door frame. The tongue 26 is then slid into the groove 22 and the round-headed screws are now applied to anchor the holder in place, and also to provide a stop for the knob 28 to prohibit the slide 26 from falling out when the inserts are not in the frame.

To apply the insert the tongue members H are first engaged through the wearplates l9 into the recess l8 in the bottom rail of the insert.

Then the insert is in such position that the bolts 28 align withthe recess 29 in the sides of the side stiles of the inserts l2, Thereupon the bolts are slid toward each other until the knobs 2B are stopped by the round-headed screws 25 in which position the bolts have passed through the wearplates 30 and engaged in the recesses 29 to removably hold the insert in position.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation. r

What is claimed is:

In a fastening device having a holder provided with a channel, lateral wings extending in the same plane about the channel, and screws engaged through the wings for securing the holder to a support, a bolt slidably received in the channel, one end of the bolt having a narrow tongue formed integral therewith extending between the wings perpendicular to the bolt, the tongue terminating in a flat knob engaging the outer faces of the wings and adapted to engage said screws and limit sliding movement of the tongue in the channel in one direction.
